It is the thi
28、rd edition of NMX-J-548-ANCE, the third edition of CSA C22.2 No. 188, and the sixth edition of UL 486C. This harmonized standard has been jointly revised on January 20, 2016. This harmonized standard was prepared by the Association of Standardization and Certication (ANCE), the CSA Group, and Underw
29、riters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Committee for Connectors, of the Council on the Harmonization of Electrotechnical Standards of the Nations of the Americas (CANENA), are gratefully acknowledged. This Standard is considered suitable for use for con
30、formity assessment within the stated scope of the Standard. The present Mexican standard was developed by the SC 20D - Conectadores part of the CT 20 - Conductores from the Comite de Normalizacion de la Asociacion de Normalizacion y Certicacion, A.C., CONANCE, with the collaboration of the connector
31、s manufacturers and users. This standard was reviewed by the CSA Subcommittee on Wiring Devices for Household and General Use, under the jurisdiction of the CSA Technical Committee on Wiring Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formall
32、y approved by the CSA Technical Committee. This standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. Application of Standard Where reference is made to a specic number of samples to be tested, the specied number is to be considered a minimu
33、m quantity. Note: Although the intended primary application of this standard is stated in its scope, it is important to note that it remains the responsibility of the users of the standard to judge its suitability for their particular purpose. Level of harmonization This standard uses the IEC format
34、 but is not based on, nor is it to be considered equivalent to, an IEC standard. This standard is published as an equivalent standard for ANCE, CSA Group, and UL. An equivalent standard is a standard that is substantially the same in technical content, except as follows: Technical national differenc
35、es are allowed for codes and governmental regulations as well as those recognized as being in accordance with NAFTA Article 905, for example, because of fundamental climatic, geographical, technological, or infrastructural factors, scientic justication, or the level of protection that the country co
36、nsiders appropriate. Presentation is word for word except for editorial changes. Reasons for differences from IEC The Technical Harmonization Committee identied several IEC standards that address electrical wire connectors included in the scope of this standard. The IEC standards for electrical wire
37、 connectors are recognized as being generally system-specic, containing the requirements for the relevant wire connectors and cables in many discrete IEC standards.

38、BUTION WITHOUT PERMISSION FROM UL The THC determined the safe use of electrical wire connectors is dependent on the design and performance of the wire connectors in relation to the North American electrical codes with which they are intended to be installed. The THC agreed such future investigation
39、would be facilitated by the harmonization of the North American electrical codes for wire connectors with IEC installation practices. Interpretations The interpretation by the standards development organization of an identical or equivalent standard is based on the literal text to determine complian
40、ce with the standard in accordance with the procedural rules of the standards development organization. If more than one interpretation of the literal text has been identied, a revision is to be proposed as soon as possible to each of the standards development organizations to more accurately reect
41、the intent.

42、 for use with all alloys of copper, aluminum conductors, or copper-clad aluminum conductors, or all three, in accordance with the Canadian Electrical Code Part I, C22.1, in Canada, the National Electrical Code, NFPA-70, in the United States of America, or the Standard for Electrical Installations, N
43、OM-001-SEDE, in Mexico, as follows: Note: Copper-clad aluminum conductors are for use only in the United States in accordance with the National Electrical Code, NFPA 70. a) connectors intended to hold two or more conductor(s); b) connectors intended for use in appliances and equipment that comply wi
44、th the requirements for such appliances and equipment; c) connectors intended for use with 6 AWG (13.3 mm 2 ) or smaller conductors; and d) uninsulated connectors that are used in circuits rated 8 000 V and less. Note: Examples of splicing wire connectors include twist-on connectors, insulation-pier
45、cing or displacement connectors, spring-action connectors, tool-applied crimp, mechanical set-screw connectors, etc. 1.2 This Standard is intended for splicing wire connectors suitable for use with conductors in the size ranges as follows: a) Aluminum: 1) 12 AWG (3.3 mm 2 ) and 10 AWG (5.3 mm 2 ) so
46、lid; 2) 12 AWG (3.3 mm 2 ) to 6 AWG (13.3 mm 2 ) stranded, Class B concentric, compressed, and compact; and 3) 12 AWG (3.3 mm 2 ) to 6 AWG (13.3 mm 2 ) stranded single input wire (SIW). In Mexico, the use of aluminum conductors is permitted only with thermoset insulation and for sizes of 6 AWG (13.3
47、 mm 2 ) and higher. b) Copper-clad aluminum: 1) In Canada, this construction is not allowed. 2) In Mexico, this construction is not allowed. 3) In the United States: i) 12 AWG (3.3 mm 2 ) and 10 AWG (5.3 mm 2 ) solid; and ii) 12 AWG (3.3 mm 2 ) to 6 AWG (13.3 mm 2 ) stranded, Class B concentric, com
48、pressed, and Class C concentric. c) Copper: JANUARY 11, 2013 NMX-J-548-ANCE CSA C22.2 NO. 188-13 UL 486C 7UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 1) 30 AWG (0.05 mm 2 ) to 10 AWG (5.3 mm 2 ) solid; and 2) 30 AWG (0.05 mm 2 ) to 6 AWG
49、 (13.3 mm 2 ) stranded, Class B concentric and compressed, and Class C concentric. d) Compact-stranded copper conductors: In Canada and Mexico, for 8 AWG (8.4 mm 2 ) and 6 AWG (13.3 mm 2 ). In the United States this is not applicable. e) Rigid (solid and stranded) metric wire falling within the ranges of the above AWG sizes. Note: For example, a connector rated for 6 AWG (13.3 mm 2 ) 14 AWG (2.1 mm 2 ) may be additionally rated for 10 2.5 mm 2 .
